The invention provides a blind area pre-collision target detection method, a vehicle-mounted millimeter wave radar, a product and a vehicle, and the method comprises the steps: receiving a radar echo signal, and processing the radar echo signal to obtain point cloud data; performing target clustering on the point cloud data, and determining a target and information of the target; determining a dynamic target shielded by a static target as a potential early warning target according to the information of the target in the detection area range; and determining a blind area pre-collision target from the potential early warning targets according to the multipath reflection point cloud of the potential early warning targets and the motion direction of the potential early warning targets. According to the method, the pre-collision target in the blind area can be accurately detected by utilizing the multipath effect of the radar under the condition of not additionally increasing radar hardware setting, so that the occurrence of a ghost probe accident can be reduced, and the auxiliary driving performance is improved.
